F-statistics corroborated the low level of geographical
structure among these samples (Table 4), as only one significant
FST value was observed (at locus Pse101), and over
all loci neither FST nor RST was significantly different from
0. The relatively higher values of FIS and FIT reflected the
deviations from HWE found with these data. The amova
analysis corroborated the weak large-scale differentiation.
